My invention relates tov dish washing inachines and has for its objectto provide a com pact and easily operated machine which will 'screenwhich forms theinside wall of adishf holding compartment ;V and Fig. is'asecti'onal view forsilverwa're." My improved machine comprlses a sheetmetal tank 6,.rectangular in horizontal secfai-basket use@ Vtion, andsupported on legs-7,8. Said tank 1s provided with a Vf-shaped bottom 9,at one end of the valleyof which is an outlet opening through which'thewater in the tank may be drawn olfwhen desired.- Said outlet isnormally-closed by a cylindrical plug 11v having near its upper end anoverflow opening 12 whichlimits the dpth of the water inl the tank. Thelower en of this plug telescopes into the' opening 10, as shown in Fig.

3, so that the outlet 10 guides' the plug when it is movedverticallytoward' or from its seat.

At its opposite end itisprovided with a latch 33 adapted to engagea-keeper 34 securedto the tankto holdthe cover in tion. throughf an' arc of'180- zontal thereb ticlesso as to occupy horipos1t1on. at one side of the tank, andV fore theyare placed in the machine or after they are removed therefrom, andinlorder to support the cover when it is in its` opened position, as wellas to guide it while being moved from one position to another, a bail 35is provided, the .ends of which are c011- .nected with'the oppositesides of the cover 31 between'its ends, while the intermediate orloopedportion of' the bail extends across one end of the tank outsidethereof between guides or straps '36, best shown' in Figs.4 1 and' 3.

These stra coopera-te with the lwall of the tank to whlch'they areattached to form loops long enough to accommodate the movement of thebail incident to theI swinging ofthe cover as itis moved` from one ofits positions to the other. By this construbtion-the bail, orequi'valent device, forrns a brace which iirmly supports the cover whenitis in its open position, thereby making it capable of sustaining suchloads as would ordinarily be placed upon it.

its closed posil. The cover 1s adapted toI be swung 8hA serve as a trayor table to support ari and operate to throw the water throughout vItalso supports the cover laterally when it is -being'sw-ung from oneposition to the other. 55 distributing it throughout vall lparts of theIn the upper portion of, the tank arefpro- 110 vided corner brackets 37fiXedly secured to the walls of the tank for the purpose of supporting abasket adapted to carry articles such as plates, saucers, cups, &c. Thisbasket is of suitable dimensions to extend across fiat member 39composed of a metal rod bent `to the proper shape and having its endswelded together. This member forms the' bottom of the basket and restson longitudi nally extending rods 38a or equivalent supports carried bythe frame 38. It. carries a series of parallel cross-rods 40, 41, 42, 43the ends of which are iixedly connected with the side portions of themember 39, preferably by spot welding.y The rods 40, 41 are providedwith a series of equally spaced vertical rods or fingers 44, 45 whichcooperate to support the smaller dishes, such as saucers, while the rods42, 43 have a corre- Lsponding series of vertical rods or `ngers 46, 47which cooperate to support similar larger dishes, the spaces betweenconsecutive rods 46, 47 bein wider than those between the rods 44,-45.lso the rods 42, 43 are preferably spaced'further apart than the rods40, 41 as clearly shown in Fig. 2. 48 indicates a series oflongitudinally extending rods which brace the several rods 40, 41,42 andl43. It is not intended that dishes be placed in the spaces between therod 43 and the adjacent end wall of the basket, thus leaving open spacesA, B through which water can ass more freely than between the dishescarried by the basket. The purpose yof .this is to permit a-part ofthewash water to pass comparatively freely up above the dishes in thebasket so that it can fall more efectively on the dishes in the basket.The end portion of the bottom 39'between the rod 40 and the adjacent endof the frame 38 is of reticulated construction, as .shown at 49,so'thatdit is adapted to support small or irregularly shaped articleswhich cannot well be placed between the upright fingers of the basket,this reticulated portion being preferably formed of a series oflongitudinal land cross rods 50, 51, as shown at the left inFig. 2. Thebasket asa whole, may be readily removed and replaced as the frame 38rests loosely on the corner brackets 37, and is 'provided with handles38h, 4or the bottom 39 may be' separately removed to give access to thelower portion of the tank.

Below said basket at one endof the tank is a plate holding basket 52comprising iaring U-shaped rods 53 which form the end members of thebasket, a rectangular rod 54 connected with the upper or outer ends ofthe members 53, longitudinal rods 55' connected with the members'53 atthe angles thereof and extending longitudinally of the basket,

and a series of perpendicular rods 56 rising `from the rods 55, at shortintervals apart,

to about the level of the frame 54. All these l parts are fixedlysecured together, preferably by spot welding, sp that they form anopenwork basket wider.. at the to than at the bottom and having a serieso parallel Iperpendicular rods well adapted to receive and retain plateson edge. -As shown in Fig. 1, one side of the frame 54 is adapted tohook yover clips 57 secured to the sidewall of the $13,111- ported 1nposition at one side of the pad e wheel shaft and below the positionoccupied by the basket 38, the plates being thus presented edgewise tothe paddles so that water may be thrown between them.

At the opposite end of the tank below thev position occupied by thebasket 38 and at a short distance from the wall of the tankv are uprightguides 58 secured to the side walls of the tank and adapted to receiveand su port a screen 59, the lower margin of whic when in position,rests on. the bottom of the tank. This screen is best shown in Fig. 4and comprises a substantially rectangular framework 60 having legs 61which are adapted. to rest on thev bottom of the tank. Across thisframework extend horizontal and vertical rods 62, 63 to form areticulated screen through which water may pass freely. This screencooperates with the adjacent end wall of the tank and -withthat portionof the bottom 9 lyin between them to form a compartment whic extendsentirely across one end ofthe tank and is ada ted to receive articlessuch as plattersy whic cannot conveniently be accommodated in thebaskets 4already described.

For receivmg silverwarel rovide a cylinlio dr'ical basket 64, the endsof w 'ch are formed 68 is connected wit the rod 66 at suitable intervalsby links 70, as shown in Fig. 5. This silverware basket is placedloosely 1nA the tank in an convenient location where -it will not interere with the rotation of the paddles. 71 indicates a clipsecured to oneof the side walls of the tankfor holding up out of the way the electriccord leadin to the motor.

By the constructlon described I provide a washing machine in which thereis practicalf ly no waste space, and therefpre it has great capacity forits size, with consequent economy in cost of manufacture. .Thecomparatively small size of the machine is also advantaj )ed maybeplaced either before or after wash-y lto secure by Letters Patent, is-

geous because of the limited available space in many housesoir-apartments. The cover con'- struction provides a tight closure forthe tank during washing operations and also a convenient table on whichthe dishes to be treat- 1mg. I l

What I claim as my invention andilesire 1. The combination of a' tankopen atthe top, a cover adapted to 'tightly close said opening, a hin4et connection between said cover and the ta arranged to vpermit thecover .to swing either to its closed position or to asubstantiallyhorizontal) open position, and a bail mounted on the tank and connectedwith v "the cover to swing therewith, for supporting l cover to swingeither to its closed position or to a substantially horizontal openposition a bail -pivotally cdnnectedat one end with t e cover, theintermediate portion of said bail extending alongside the tank, and astrap carried by the tankv and loosely embracing said bail to permitverticalmovement of the lower end.' portion thereof.
